PK Sir,

Well the cost break down

Party : 500 *700=350 K +~= 500 K ( other party)
Band:                  =30   K
Gold                    =500 K (12 tola*40K)
Dress                 =300 K
Gifts                    =100 K
Accessories      =300 K
Mics                    =200  K
Total                    = ~= Uncertainty +- 20 % so ~= 2000 K seems you will be in ur budget limit if u stick to those breakdowns

OTHERWISE 
I just have a ONELINER 
i.e.
DEPENDS !
